Struct Vector

pub struct Vector<I, T>
where
    I: Idx,
{
    vector: IndexVec<I, Option<T>>,
    real_len: usize,
}

Indexed vector. To prevent accidental id reuse, the vector supports reserving a slot to be filled later.

Fields

vector: IndexVec<I, Option<T>>

real_len: usize

The number of non-None elements.
